Let's divide 25913199 by 89
The aim is to understand the frequency of 89 in 25913199.

Advancing to step 1:
If we divide 2 by 89, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 89

Going ahead to step 2:
89 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 89

Step 3:
89 can be fit into 259 2 times, resulting in a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 178 from 259, we get 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 89

Step 4:
811 divided by 89 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 801 from 811, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 89

Let's proceed to step 5:
103 divided by 89 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtracting 89 from 103 leaves us with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 89

On to step 6:
89 can be fit into 141 1 times, resulting in a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 2911.0
Subtract 89 from 141 to get 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 89

Let's proceed to step 7:
The number 89 fits into 529 5 times, leaving a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 29115.0
If we take 445 away from 529, we end up with 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 89

Let's proceed to step 8:
89 can be fit into 849 9 times, resulting in a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 291159.0
Subtract 801 from 849 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
If we divide 480 by 89, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 291159.5
If we subtract 445 from 480, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
89 goes into 350 3 times with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 291159.53
The remainder is 83 after subtracting 267 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 11:
830 divided by 89 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 291159.539
If we take 801 away from 830, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
89 can be fit into 290 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 291159.5393
The remainder is 23 after subtracting 267 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
230 divided by 89 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 291159.53932
Deduct 178 from 230 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
The number 89 fits into 520 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 291159.539325
Subtract 445 from 520 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 15:
If we divide 750 by 89, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 291159.5393258
Subtract 712 from 750 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 16:
380 divided by 89 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 291159.53932584
If we subtract 356 from 380, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 291159.53932584, and the remainder is 2.4e-08.
